CentOS 6.5 KVM gPXE to iPXE emulation failed (mmio) rip 3d6 f2 af 83 c7 - theOtherGuy - 2014-09-09 01:38
Long story short, I setup KVM on a CentOS 6.5 hypervisor. Using virt-install to start the VM, it never gets past iPXE and just gets stuck.
I even rebult an undionly.kpxe file to boot into shell, but it still gets stuck. Does anybody have an insight on what I'm doing wrong?

Change the PXE ROM used by your hypervisor. Either upgrade the hypervisor package to something more recent (which uses iPXE rather than gPXE), or replace the .rom file with one built from the current iPXE codebase.
